论文摘要
假设ZFC。令$κ$为红衣主教。 A $ {<κ} $ - 地面是一种及时的适当类$ W $建模ZFC,因此$ v $是通过强迫$ \ MATHBB {p} \ in w $ of Cardinality $ {<κ} $的$ w $的通用扩展。 $κ$ - mantle是所有$ {<κ} $ - 地面的交集。我们证明,$κ$ - 摩托车中的某些部分选择原则是$κ$无法访问/弱紧凑的结果,以及其他一些相关事实。
Assume ZFC. Let $κ$ be a cardinal. A ${<κ}$-ground is a transitive proper class $W$ modelling ZFC and such that $V$ is a generic extension of $W$ via a forcing $\mathbb{P}\in W$ of cardinality ${<κ}$. The $κ$-mantle is the intersection of all ${<κ}$-grounds. We prove that certain partial choice principles in the $κ$-mantle are the consequence of $κ$ being inaccessible/weakly compact, and some other related facts.
